developer tools

Tomte is a Go toolkit for building small, single-purpose AI agents that run on a schedule or on demand. The page shows deployment, runtime limits, example code, and a concrete invoice-chasing use case.

A finite volume solver for the 1D Saint-Venant (shallow water) system with topography, using a kinetic scheme with reflections and a comparison Rusanov scheme.

Skillstore is a searchable skills library for Claude Code and Codex that delivers task-specific instructions and supporting files through MCP. It also lets teams create, share, and improve their own methods with feedback.

VoiceGremlin is a CI/CD testing tool for AI voice agents that places real phone calls, evaluates results through an API, and returns pass/fail outcomes with transcripts.

An open source headless SaaS backend built for agents and assistants, with records, files, accounts, permissions, notifications, and audit logs accessible through MCP, CLI, or API.

Pinrail is a desktop app that lets coding agents pause for human review before taking action. It supports structured decisions, works with several agent tools, and includes plugin-based review views for code, lists, feedback, markdown, and images.

Spens is a developer tool for running coding agents in sandboxed Docker containers with network controls, secret handling, and detailed logs of LLM calls, tool use, and file changes.

Weekly tracking for whether ChatGPT, Perplexity, Google AI Overviews, Gemini, and Claude cite your site, name your brand, or leave you out. The page shows pricing, the report structure, example outputs, and how the system works.

DrivingBench is a benchmark that tests frontier LLMs on real-world driving tasks in a Toyota Corolla with a cone course, leaderboard, run traces, and replay videos.

A Claude Code plugin and MCP-based project-state tool that keeps decisions, constraints, rejected paths, and other session context versioned in git so AI sessions can resume consistently.

Errand is an open-source macOS app for working with persistent AI teammates that each have their own cloud computer, conversation history, and files. The page shows the product purpose, how it works, download availability, and a visible FAQ explaining setup and runtime requirements.

aclif is an open-source Agent CLI framework for building command-line tools that AI agents can use across SaaS platforms. It emphasizes one shared grammar, canonical names, introspection, safety metadata, and multiple runtime modes including shell, tool call, and gateway.

A macOS menu-bar app that supervises MCP servers so multiple editors and clients can share one running server per profile, with credentials stored in Keychain and tool calls recorded.

Bastiontrace is a Python library for analyzing AI agent tool-call traces to locate prompt injections, identify where they landed, and map the resulting blast radius.

An evidence-aware mathematics runtime for LLMs and a Python/MCP server. It combines exact, symbolic, formal, certified-interval, and numeric computation with typed outputs, trust labels, and provenance tracking.

A CLI and TypeScript helper that lets coding agents turn MCP tool usage into scripts, with typed APIs and a skill for Claude projects.

A macOS feedback layer for coding agents that captures comments on text, screenshots, web elements, and voice, then passes them to agents through MCP with attached context.

TokenSpend tracks AI coding spend and ties it back to shipped work, with GitHub-based PR attribution, team-level reporting, and a live model router with receipts.

ModelPlane is an OpenAI-compatible AI gateway that routes requests across multiple model providers through one endpoint. It includes model groups, fallback and weighted routing, multiple provider support, reasoning output normalization, and usage/billing tracking.

TokenMaxxer is a CLI-based AI usage tracker for developers that reads token counts from tools like Claude Code, Codex, Cursor, and others, then shows spend, model usage, and a public leaderboard. It emphasizes local-only reads and opt-in sharing.

AI forecasting platform with a public track record, API/docs, and integrations for Claude Desktop and Claude Code. The page highlights benchmark results, live market usage, and example forecast types for probability, numeric, date, categorical, and decision questions.

Local-first coding agent that runs on the user’s machine and can work across the browser, desktop, terminal, and editor surfaces. The repo says it verifies fixes by reproducing failures and re-running assertions, with install instructions for Windows, macOS, and Linux.

NoWreck is a CLI verifier that checks whether AI coding assistant claims match the actual code changes using structural analysis rather than another model judgment.

CLI and TypeScript SDK for finding, validating, and fixing security vulnerabilities in code, with repository scanning, change review, finding history, and CI support.
